Phytotoxic Assessment of Agno3 and Znso4 Vis À Vis Agnps and Znonps in Tagetes Erecta L. and Zinnia Elegans Jacq
Year: 2021
Type: article
Abstract: The present study was intended to assess the comparative responses of the two asteraceous plants, Mexican marigold (Tagetes erecta L.) and zinniasp.(Zinnia elegans Jacq.) against silver nanoparticles (AgNPs) and zinc oxide nanoparticles (ZnONPs) and their respective salts, silver nitrate (AgNO 3 ) and zinc sulphate (ZnSO 4 ) by assessing different growth parameters, oxidative stress biomarkersand anti-oxidative defense system.Metal salts were found to be more toxic than their nanoparticles, which was manifested in terms of more reductions in growth parameters and more enhancements in reactive oxygen species along with MDA equivalents content.Further, various antioxidant enzymes viz.superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and glutathione-S-transferase (GST) enhanced significantly but not at the level that minimizes the oxidative stress.
